Post-weld heat treatment provides a solution for the rigorous conditions encountered by welded components in power generation, petrochemicals and refining industries. By relieving residual stresses and improving mechanical properties of these components, post-weld heat treatment ensures they meet safety and regulatory standards.

These processes often incur high energy costs and require long periods of time at specific temperatures; however, they can often be completed on-site to cut transportation costs and risks associated with transporting such large objects.

Cost-Effective

Post weld heat treatment is an essential process in maintaining the integrity, reliability and safety of welded components in the oil and gas industry. It relieves residual stresses while improving mechanical properties and corrosion resistance – as such it is an integral step towards regulatory compliance and upholding industry standards in such harsh operating environments.

PWHT services on-site help reduce costs and save time, since it eliminates the need to transport large items between locations, which reduces risks to employees while moving these heavy products. In addition, services can be performed in an enclosed environment which protects equipment and welders from weather and environmental conditions.

TEAM utilizes cutting-edge technology and an experienced team of engineers to deliver comprehensive on-site heat treatment services that optimize materials while meeting industry requirements. TEAM’s range of heat treatments span from solution annealing of stainless steel, expansion heating, quenching and tempering and their proprietary Axi-Therm blended heating and cooling technologies as well as our Axi-Therm blended heating/cooling processes – with enough expertise and resources available to us to fulfill any PWHT need that may arise.

On-Site

Post-weld heat treatment (PWHT) is an easy and cost-effective service that strengthens welded joints by relieving stress and tension from them, an integral component of maintaining equipment. There are various on site PWHT services available for any kind of steel product imaginable; they help save you money by eliminating shipping expenses as they help ensure all items receive appropriate treatment.

Specialist PWHT services can reduce residual stresses and enhance weld microstructure, increasing lifespans of pipes, pressure vessels, towers and equipment. In addition to reducing residual stresses, these services also prevent cracking in welds and corrosion of steel components as well as hydrogen-induced cracking by preheating materials ahead of time. Providing this service on-site provides many companies with convenient service solutions.

Безопасност

Tanks, vessels and piping used in the oil industry require stringent reliability and safety standards that require post weld heat treatment (PWHT) services to remain structurally sound for years to come in harsh environments. Therefore PWHT services are essential to guaranteeing this long-term viability of these large structures.

PWHT relieves residual stresses created during welding, improving weld microstructure and avoiding cracking. Furthermore, PWHT tempers the metal and reduces its hardness thereby decreasing risk of brittle fracture and increasing resistance to stress and corrosion.

Libratherm offers PID Ramp Soak controllers designed specifically to monitor PWHT processes with pinpoint precision, so the temperature of steel across its entirety remains consistent – eliminating hot spots which could otherwise lead to damage or failure. This ensures accurate results.
